Randomised clinical trial of physiotherapy after open abdominal surgery in high risk patients

Postoperative physiotherapy has been shown to reduce the incidence of postoperative pulmonary complications after open abdominal surgery. This study aimed to determine if the addition of deep breathing exercises and secretion clearing techniques to a standardised physiotherapist-directed program of early mobilisation improved clinical outcomes in patients undergoing open abdominal surgery. Fifty-six patients undergoing open abdominal surgery, at high risk of developing postoperative pulmonary complications, were randomised before operation to an early mobilisation-only group or an early mobilisation-plus-deep breathing and coughing group. Mobility duration, frequency and intensity of breathing interventions were quantified for both groups. All outcomes were assessed by a blinded outcomes researcher using a standardised outcomes measurement tool developed specifically for this population. Outcomes included incidence of clinically significant postoperative pulmonary complications, fever, length of stay, and restoration of mobility. There were no significant differences between groups in mean age, anaesthetic time, perioperative morbidity, or postoperative mobility. Outcome data were available for 89% of enrolled subjects. Overall incidence of postoperative pulmonary complications was 16%. The incidence of postoperative pulmonary complications in the non-deep breathing and coughing group was 14%, and the incidence of postoperative pulmonary complications in the deep breathing and coughing group was 17%, (absolute risk reduction -3%, 95% C1 -22 to 19%). There was no significant difference between groups in the incidence of fever, physiotherapist time, or the number of treatments. This study suggests that, in this clinical setting, the addition of deep breathing and coughing exercises to a physiotherapist-directed program of early mobilisation does not significantly reduce the incidence of clinically significant postoperative pulmonary complications in high risk open abdominal surgery subjects.

Pulmonary rehabilitation in Australia: a national survey

OBJECTIVE To determine the current structure and content of pulmonary rehabilitation programs in Australia. DESIGN A cross sectional, observational design using a purpose designed anonymous written survey. SETTING AND PARTICIPANTS The National database of Pulmonary Rehabilitation Programs maintained by the Australian Lung Foundation was used to identify all known programs in all states and territories of Australia (n=193). All pulmonary rehabilitation programs listed on the database were included. Respondents were health professionals who coordinated programs. RESULTS The response rate was 83% (161/193). Programs were coordinated by physiotherapists (75/147, 51%) and/or nurses (49/147, 33%), were hospital based (97/147, 66%) and ran for 8 weeks or longer (95/147, 65%). Pre (145/147, 99%) and post (137/147, 93%) program assessment was undertaken using a variety of measures. The Six Minute Walk Test (138/147, 94%) was the most commonly used test of exercise capacity. Exercise training was included in 145 programs (99%). Most patients attended at least two supervised exercise sessions per week (106/147, 72%) and exercised for at least 20 minutes (135/147, 92%). Lower limb endurance, upper limb endurance, strength training, and stretching/flexibility exercises were the most commonly included modes of exercise. Intensity prescription for exercise training was variable. Many respondents (93/147, 63%) indicated that they perceived a gap between their clinical practice and current evidence. CONCLUSIONS Pulmonary rehabilitation programs in Australia generally meet the broad recommendations for practice in terms of components, program length, assessment and exercise training. The prescription of exercise training intensity is an area requiring deeper exploration.

Management of Sternal Precautions Following Median Sternotomy by Physical Therapists in Australia: A Web-Based Survey

Background Sternal precautions are utilized within many hospitals with the aim of preventing the occurrence of sternal complications (eg, infection, wound breakdown) following midline sternotomy. The evidence base for sternal precaution protocols, however, has been questioned due to a paucity of research, unknown effect on patient outcomes, and possible discrepancies in pattern of use among institutions. Objective The objective of this study was to investigate and document the use of sternal precautions by physical therapists in the treatment of patients following median sternotomy in hospitals throughout Australia, from immediately postsurgery to discharge from the hospital. Design A cross-sectional, observational design was used. An anonymous, Web-based survey was custom designed for use in the study. Methods The questionnaire was content validated, and the online functionality was assessed. The senior cardiothoracic physical therapist from each hospital identified as currently performing cardiothoracic surgery (N=51) was invited to participate. Results The response rate was 58.8% (n=30). Both public (n=18) and private (n=12) hospitals in all states of Australia were represented. Management protocols reported by participants included wound support (n=22), restrictions on lifting and transfers (n=23), and restrictions on mobility aid use (n=15). Factors influencing clinical practice most commonly included “workplace practices/protocols” (n=27) and “clinical experience” (n=22). Limitations The study may be limited by response bias. Conclusions Significant variation exists in the sternal precautions and protocols used in the treatment of patients following median sternotomy in Australian hospitals. Further research is needed to investigate whether the restrictions and precautions used are necessary and whether protocols have an impact on patient outcomes, including rates of recovery and length of stay.

How prepared are rural and remote health care practitioners to provide evidence-based management for people with chronic lung disease?

OBJECTIVE To investigate the existing experience, training, confidence and knowledge of rural/remote health care practitioners in providing management for people with chronic obstructive pulmonary disease (COPD). DESIGN   Descriptive cross-sectional, observational survey design using a written anonymous questionnaire. This study formed part of a larger project evaluating the impact of breathe easy walk easy (BEWE), an interactive education and training program for rural and remote health care practitioners. SETTING Rural (n = 1, New South Wales) and remote (n = 1, Northern Territory) Australian health care services. PARTICIPANTS Health care practitioners who registered to attend the BEWE training program (n = 31). MAIN OUTCOME MEASURES Participant attitudes, objective knowledge and self-rated experience, training and confidence related to providing components of management for people with COPD. RESULTS Participants were from a variety of professional backgrounds (medical, nursing, allied health) but were predominantly nurses (n = 13) or physiotherapists (n = 9). Most participants reported that they had minimal or no experience or training in providing components of management for people with COPD. Confidence was also commonly rated by participants as low. Mean knowledge score (number of correct answers out of 19) was 8.5 (SD = 4.5). Questions relating to disease pathophysiology and diagnosis had higher correct response rates than those relating more specifically to pulmonary rehabilitation. CONCLUSION The results of this study indicate that some rural and remote health care practitioners have low levels of experience, knowledge and confidence related to providing components of management for people with COPD and that education and training with an emphasis on pulmonary rehabilitation would be beneficial.

Establishing and delivering pulmonary rehabilitation in rural and remote settings: The opinions, attitudes and concerns of health care professionals.

OBJECTIVE Pulmonary rehabilitation is recommended for people with chronic lung disease however access remains limited in rural and remote settings. The aim of this project was to explore the perspectives of rural and remote health care professionals regarding the establishment and delivery of pulmonary rehabilitation. SETTING Rural (NSW) and remote (NT) Australian healthcare settings. PARTICIPANTS Health care professionals (n = 25) who attended a training program focussing on the delivery of pulmonary rehabilitation. MAIN OUTCOME MEASURE(S) Surveys with open written questions were completed by participants following the training program. Key informants also participated in face-to-face interviews. Thematic analysis was undertaken of data collected on participant opinions, attitudes and concerns regarding the establishment and delivery of pulmonary rehabilitation in their individual situation. RESULTS Participating health care professionals (predominantly nurses and physiotherapists) identified a number of issues relating to establishing and delivering pulmonary rehabilitation; including staffing, time and case load constraints, patient and community attitudes, lack of professional knowledge and confidence and inability to ensure sustainability. The practicalities of delivering pulmonary rehabilitation, particularly exercise prescription and training, were also important concerns raised. CONCLUSIONS Lack of health care professional staffing, knowledge and confidence were reported to be factors impacting the establishment and delivery of pulmonary rehabilitation. This study has facilitated a greater understanding of the issues surrounding the establishment and delivery of pulmonary rehabilitation in rural and remote settings. Further research is required to investigate the contribution of health professional training and associated factors to improving the availability and delivery of pulmonary rehabilitation in rural and remote settings.

Does Delivery of a Training Program for Healthcare Professionals Increase Access to Pulmonary Rehabilitation and Improve Outcomes for People with Chronic Lung Disease in Rural and Remote Australia

OBJECTIVE Access to pulmonary rehabilitation (PR), an effective management strategy for people with chronic respiratory disease, is often limited particularly in rural and remote regions. Difficulties with establishment and maintenance of PR have been reported. Reasons may include a lack of adequately trained staff. There have been no published reports evaluating the impact of training programs on PR provision. The aim of this project was to evaluate the impact of an interactive training and support program for healthcare professionals (the Breathe Easy, Walk Easy (BEWE) program) on the delivery of PR in rural and remote regions. METHODS The study was a quasi-experimental before-after design. Data were collected regarding the provision of PR services before and after delivery of the BEWE program and patient outcomes before and after PR. RESULTS The BEWE program was delivered in one rural and one remote region. Neither region had active PR before the BEWE program delivery. At 12-month follow-up, three locally-run PR programs had been established. Audit and patient outcomes indicated that the PR programs established broadly met Australian practice recommendations and were being delivered effectively. In both regions PR was established with strong healthcare organisational support but without significant external funding, relying instead on the diversion of internal funding and/or in-kind support. CONCLUSIONS The BEWE program enabled the successful establishment of PR and improved patient outcomes in rural and remote regions. However, given the funding models used, the sustainability of these programs in the long term is unknown. Further research into the factors contributing to the ability of rural and remote sites to provide ongoing delivery of PR is required.

Discordance Between Distance Ambulated as Part of Usual Care and Functional Exercise Capacity in Survivors of Critical Illness Upon Intensive Care Discharge: Observational Study

Background People who have had a prolonged admission to an intensive care unit (ICU) commonly have profound debilitation and weakness. For the delivery of effective exercise training, an accurate assessment of exercise capacity is essential. Objective The study objectives were to investigate how much ground-based walking is undertaken by inpatients recovering from critical illness within 1 week of discharge from an ICU and to evaluate the feasibility and safety of the Six-Minute Walk Test (6MWT) for this population. Design This was an observational study. Methods Within 1 week of discharge from the ICU, functional exercise capacity was measured with the 6MWT. The maximum distance ambulated on the ward in a single session as part of usual clinical management was extracted from the medical notes. The distance achieved during the 6MWT and the maximum distance ambulated on the ward were compared. Results The participants (N=23) were survivors of a critical illness; their mean age was 57 years (SD=11). The median length of ICU stay was 11 days (interquartile range [IQR]=7). The mean 6-minute walk distance (6MWD) was 179 m (SD=101), and the maximum distance ambulated on the ward was 30 m (IQR=65). There was a moderate association between the distance participants ambulated on the ward and the 6MWD (r=.54). The maximum distance ambulated on the ward, expressed as a percentage of the 6MWD, was 29% (IQR=34%). Five participants (22%) experienced oxygen desaturation (oxygen saturation of <85%) and recovered within 1 minute of resting. Limitations The maximum distance ambulated on the ward was estimated with premeasured distances. Conclusions Most participants ambulated at a low percentage of their measured exercise capacity. The 6MWT appears to be a safe and useful test for inpatients recently discharged from the ICU.
